Description

handle unit

The invention relates to a handle unit for actuating a lock of a movable part of a motor vehicle, in particular a vehicle door, flap or the like, with a movable handle element, which can be brought into a rest position and an actuating position, and a stationary element, wherein at rest, a gap between the gripping element and the stationary element is present, and the gripping element has a leg which extends through an opening and in the actuated position triggers an activation of the lock. A variety of handle units with a movable handle member and a stationary member disposed adjacent to the movable handle member are known to those skilled in the art. Disadvantageously, it has been shown that, especially at high speeds of the motor vehicle, disturbing noise developments can occur on and within the grip unit.

It is an object of the present invention to provide a handle unit, in which the disadvantages mentioned are avoided, in particular a handle unit is provided, which is simple in design and in which annoying wind noise at higher vehicle speeds on the handle unit are almost avoided.

To solve this problem, a handle unit with the features of claim 1 is proposed. In the dependent claims preferred developments are carried out.

For this purpose, the invention provides that on the leg an acoustic element is provided for noise reduction, which prevents an air guide through the gap in the breakthrough in the rest position of the handle element. The acoustic element is arranged on the handle unit in such a way that, in the rest position of the handle element, the limb lying largely inside the movable part is completely closed by the acoustic element from the outside environment. The air can not pass through the breakthrough along the leg in the moving part of the motor vehicle due to the negative pressure forming within the gap, which forms at higher speeds of the motor vehicle. Thus, Windverwirbelungen can be avoided within the movable part, which is simultaneously associated with a substantial reduction of the noise in the prior art perceived as disturbing to the handle unit.

In one possible embodiment of the invention, a sliding element is arranged peripherally on the leg. This sliding element serves to ensure that as possible during the movement of the handle element from the rest position to the operating position and vice versa little noise arises. Advantageously, the sliding element has a contacting surface which, during the movement of the grip element into its respective position, contacts a counter contacting surface on the stationary element within the movable part. The sliding element and the legs are thus movably mounted on the Gegenkontaktierungsfläche. The use of a "softer" plastic as the contacting surface has shown that the noise development at the contacting surface can be substantially reduced during the movement of the gripping element The contacting surface can be made of POM, PBT, PA or ABS, for example the contacting surface is a material of PBT / PC and / or ABS / PC or a mixture of the aforementioned materials.

In a further alternative of the invention, the sliding element itself is designed with the acoustic element. Here, the sliding element may be integrally and / or materially connected to the acoustic element. Alternatively, the sliding element with the acoustic element forms a two-component component.

In a further embodiment, the acoustic element can be arranged on the leg or on the stationary element. Here, in the rest position of the handle element, the acoustic element connects the leg with the stationary element. This means that the acoustic element completely closes off or covers the breakthrough, without the risk that the air guide formed during the drive of the motor vehicle passes through the opening into the inside area of the movable part.

For example, the acoustic element may be lip-shaped. In order to achieve a good contact of the acoustic element with the leg or the stationary element, the acoustic element is preferably made of a rubber-elastic plastic. This may be, for example, an elastomeric plastic.

In a measure improving the invention, the leg can be designed with a collar element on which the acoustic element rests. Here it is Acoustic element disposed between the collar member and the sliding member, wherein the acoustic element is advantageously carried out funnel-like, whereby effectively the breakthrough in the rest position of the grip element can be closed. It is possible for the leg, the sliding element and the acoustic element to be designed as a three-component component. The collar element has, inter alia, the function that the acoustic element can be reliably attached to the leg. In addition to this positioning help acting during the movement of the handle member from the rest position to the operating position and vice versa acting on the acoustic element forces can be effectively absorbed through the collar member, whereby a permanent arrangement of the acoustic element is ensured on the leg.

Advantageously, the fixed element on the inside towards the movable part towards a free end, which contacts the acoustic element in the rest position of the handle element. In this case, the acoustic element can be arranged on the movable grip element, in particular on the leg, wherein in the rest position of the grip element, the acoustic element acts directly on the free end of the stationary element. Alternatively, it is conceivable that the free end of the fixed element itself is designed as an acoustic element, which extends projecting in the direction of the adjacently arranged leg and rests there in the rest position of the handle element and thus effectively completes the breakthrough. In this embodiment, therefore, the acoustic element is indeed arranged on the leg, but directly on the stationary element of the handle unit.

The moisture seal and / or Schmutzpartikelabdichtung the handle unit is carried out in a preferred embodiment by a flat seal on the movable part, which rests sealingly in the rest position of the handle element both on the handle member and on the stationary element. Preferably, this flat seal has a circumferential sealing lip, within which the acoustic element is located. Conveniently, the seal is formed with a receiving opening through which the leg is movable into its respective position. In order to prevent impact noise when the rest position is reached, the seal has at least one projection-like stop element for the grip element. The stop element protrudes from the flat seal and serves as a buffer element, which preferably has rubber-elastic properties and at the same time leaves virtually no noise when the grip element strikes the seal.

Further advantages, features and details of the invention will become apparent from the following description in which several embodiments of the invention are described in detail with reference to the drawings. The features mentioned in the claims and in the description may each be essential to the invention individually or in any desired combination. Show it:

Fig. 6 is a three-dimensional view of the handle unit with handle member having a leg and a sliding member and

Fig. 7 shows a further three-dimensional view according to FIG. 6 on the sliding element without handle element.

In Fig. 1, a handle unit 10 according to the invention is shown purely schematically, which is attached to a vehicle door 1. The handle unit 10 is in operative connection with a provided on the door 1 mechanical lock 2. As shown in Fig. 2, the Handle unit 10, a movable handle member 11 and a stationary member 12. As can be clearly seen, the fixed element 12 is designed with a cylinder tower 12b in which a cylinder lock can be arranged. In another possible embodiment of the handle unit 10, the cylinder tower 12b may remain empty without any elements.

The movable handle element 1 1 is in a rest position and can be pulled by the user in a not explicitly shown operating position (see arrow). 2, the handle member 11 is pivoted out of the door 1 in a clockwise direction about the axis 22 during the movement of the handle member 1 1 from the rest position to the operating position. The handle member 11 is in this case designed with an arm 20 which is rotatably mounted at its free end 21 inside the door 1 about the axis 22. The free end 21 is executed in the illustrated embodiment as a one-sided open slot.

The grip element 11 has a leg 14 which extends like a finger through an opening 15 of the vehicle door 1. The opening 15 is illustrated in FIGS. 3 to 5. While the handle member 1 1 is moved with its leg 14 in the operating position by the user, activates the leg 14 inside the door 1, an action that triggers an opening operation of the lock 2. It is conceivable that, for example, the free end of the leg 14 is connected to a mechanism having a Bowden cable. The Bowden cable is in operative connection with the lock 2 of FIG. 1, so that the Bowden cable 2 activates the lock accordingly. Of course, further mechanical or electromechanical means are conceivable to activate and move the lock 2 in accordance with a movement of the handle element 1 1 and the leg 14.

As is illustrated in Fig. 2 and in Fig. 3, there is a gap 13 between the handle member 1 1 and the stationary member 12. On leg 14, an acoustic element 16 is arranged, which is lip-like and made of a rubber-elastic plastic in the illustrated Embodiments consists. This acoustic element 16 is used for noise reduction. That means that about this Acoustic element 16 an air guide 3 through the gap 13 in the opening 15 and thus in the interior of the vehicle door 1 is prevented. Thus, no wind turbulence within the vehicle door 1 while driving the motor vehicle within the door 1 arise. As a result, the comfort while driving for the user is significantly improved.

Furthermore, from FIG. 2 and from the remaining FIGS. 3 to 7, a sliding element 17 is arranged on the leg 14. This sliding element 17 has the function that during the movement of the handle element 1 1 in its respective position the least possible noise. Here, the sliding element 17 on the fixed element 12 side facing a contacting surface 17a, which touches a Gegenkontaktierungsfläche 17b on the stationary member 12 during the movement of the handle member 1 1 in its respective position. The sliding member 17 is thus slidably mounted on the Gegenkontaktierungsfläche 17 b of the fixed element 12. In the embodiments shown, the contacting surface 17a is designed with a slightly curved surface, which in addition a noiseless operation of the handle element 1 1 is favored. The sliding member 17 may be positively and / or non-positively or materially secured to the leg 14. In the present exemplary embodiments, the sliding element 17 is fastened to the leg 14 via a clip connection (latching connection), which is illustrated in FIGS. 6 and 7.

The sliding member 17 has on the inside locking elements 17c, which engage in counter-locking means of the leg 14, not shown, whereby a positive connection between the sliding member 17 and the leg 14 can be achieved. The sliding element 17 is thus placed on the leg 14 during the assembly process. In this case, the sliding member 17 on a one-sided open C-profile. In order to facilitate the assembly process, the open side of the sliding member 17 is slightly bent, in which case the leg 14 is guided through the open side of the sliding member 17.

The sliding element 17 can of course be fastened non-positively or cohesively on the leg 14 in a further alternative. For example, it is conceivable that Sliding element 17 to be arranged on the leg 14 by an injection molding process. For example, a two-component injection molding process may be used, in which the leg 14 consists of a first plastic and the sliding element 17 consists of a second plastic. The acoustic element 16 according to FIG. 3 can likewise be molded onto the leg 14.

The leg 14 has a collar element 18 according to the exemplary embodiments from FIGS. 3 to 5. In the embodiment according to FIG. 3, the acoustic element 16 rests on the collar element 18, the sliding element 17 being located above the acoustic element 16. The fixed element 12 has on the inside of the motor vehicle door 1, a free end 12a, which contacts the acoustic element 16 in the rest position of the handle element 1 1. In this embodiment, the acoustic element 16 is funnel-shaped on the circumference of the leg 14 and reliably closes the opening 15 through which the leg 14 extends.

According to the exemplary embodiments from FIGS. 3 to 7, the handle unit 10 has a flat seal 19 which, in the rest position of the grip element 11, sealingly bears against both the stationary element 12 and the grip element 11. The seal 19 has the task to effectively seal the interior of the door 1 from moisture and / or dirt particles. As can be clearly seen in Fig. 3, contacted the funnel-shaped acoustic element 16 on the one hand, the free end 12a of the stationary element 12 and the seal 19 on its underside. The seal 19 further comprises a circumferential sealing lip 19c, which is particularly illustrated in Fig. 6 and Fig. 7. This sealing lip 19c rests inter alia on the stationary element 12 and on the movable grip element 11, which can be seen in FIGS. 3 to 5.

Furthermore, the seal 19 is formed with a receiving opening 19a, through which the leg 14 can be moved to its respective position (see Fig. 6 and Fig. 7). Through this receiving opening 19a also projects the cylinder tower of the fixed element 12. The sealing lip 19c rotates around the opening through which the Leg 14 extends, and thus effectively protects the interior of the vehicle door from dirt particles or moisture can penetrate. In the embodiment according to FIG. 7, the seal 19 is designed with two projection-type stop elements 19b, which serve as buffer elements for the grip element 11.

The exemplary embodiments according to FIGS. 4 and 5 substantially correspond to the exemplary embodiment from FIG. 3, wherein in the following only the essential differences are discussed in order to avoid repetitions. The grip unit 10 according to FIG. 4 likewise has an acoustic element 16 for noise reduction, wherein the sliding element 17 is embodied uniformly in terms of material and in one piece with the acoustic element 16, even in the lower region, lying against the collar element 18. The acoustic element 16 is designed nose-like and contacted with its free end, the free end 12 a of the fixed element 12th

In the alternative embodiment according to FIG. 5, the acoustic element 16 is integrally formed on the stationary element 12 and abuts against the collar element 18 in the rest position of the grip element 11, whereby the opening 15 on the vehicle door 1 is effectively covered by the outside area without the risk that an air guide 3 passes through the gap 13 in the opening 15 and thus in the interior of the vehicle door 1.
